Just hit $120 MRR with a small SEO tool that analyzes historical Alexa Rank data—even though Amazon officially retired Alexa Internet a few years ago.
The idea came from a problem I kept running into. While researching domains and reviewing old SEO reports, I noticed that many investors, agencies, and website buyers still referenced historical Alexa Rank data. The problem was that there wasn't an easy way to access or interpret that information alongside modern SEO metrics.
Instead of letting the data disappear, I built a tool that helps users explore historical Alexa Rank trends and compare them with current website health indicators. I also included a Trust Rate metric to provide additional context for domain research and SEO audits.
What surprised me wasn't the technology—it was the demand. Domain investors use it for valuations, SEO professionals use it to understand a site's history, and marketers use it to identify long-term trends that modern metrics alone can't show.
The biggest lesson for me was that you don't always need a completely new idea to build a successful product. Sometimes, there's real value in preserving useful legacy data and combining it with modern insights.
A lot of indie hackers chase the next big trend, but I've learned that solving a small problem for a specific audience can be just as rewarding.
If you're building products, don't overlook outdated tools or discontinued services. There may still be a community that needs them—especially if you can bridge the gap between the old and the new.
Interesting result.
The thing I'd be careful with is assuming people are paying for historical Alexa data itself.
Sometimes a product starts with a legacy-data story, but customers are actually buying a different outcome entirely.
The useful part is figuring out which value users are really paying for before that story gets reinforced by more growth.
I wouldn't make that call casually in-thread because it can change positioning, acquisition, and what the product should lead with.
